[PATCH v6 00/11] PRIME Synchronization

[Alex Goins]

Hello all,

This patch set is identical to v5, except that it's rebased onto ToT, including
Dave's alternative implementation of one of my patches, commit a6b6e8ba. In the
last thread, Dave said that "with this rebased onto that, we should be pretty
much good to merge," so that is my hope.

These patches change the xserver to support setting up PRIME with double
buffering, and implement double buffered PRIME sink and source support in
the modesetting driver. In addition to these changes, I've upstreamed a
couple of patches to the i915 DRM driver that mesh with these, and have
implemented double buffered PRIME source support in the NVIDIA proprietary
driver (pending release.)
